A flash fire at a "pig receiving station" along a Eureka Hunter pipeline near Wick (Tyler County), WV last Thursday evening seriously injured three people requiring they be airlifted to Pittsburgh. A fourth person was taken to a local hospital. Sadly, one of the seriously injured workers, 56-year-old Bruce Phipps of Marietta, Ohio, died late Friday night. Pipeline Inspection Gauges (or Pigs) are used for pipeline cleaning, inspection and maintenance, and fluid batching in pipelines. A pig is pushed along the inside of a pipeline by the flow of liquid or gas. A pig launching station is used to insert the pig into a pipeline using a series of valves and hatches. The pig is pushed through the pipeline by the liquid or gas stream to the pig receiving station.
